Should I need a pre amp for one source?


I certainly don’t need one but you know usually sources usually sound better with a pre amp.
I just purchased a Cary DMS 600 streamer/player/dac.  It replaced an Aurender A10 player and a Linear Tube MZ 2.0s pre-amp with all the upgrades and the Cary sounds much better than the combo just as a stand-alone .
i have always had pre’s in my system with streamers/ Dacs  because the digital volume controls usually leave a lot to be desired 
The Cary seems to get it right. But you know....  was thinking of maybe a passive volume control?  Just don’t want to spend 3K on a pre> upgraded power cord and another set of interconnects. 
Please talk me off the edge of the rabbit hole

SYS looks good but no remote. The Ldr passives look great but again climbing back up in price. 
anything around 500-700 with a remote?

Mines only $525aud = ($354usd) posted, and that’s with the price rise, I still think and been told it’s way to cheap.

If your able to use a soldering iron you can adapt this remote volume control to it for only $24usd.
